Knowing or being able to measure the "path density" at sources of communications is essential to provide fair capacity distribution between sessions in multi-hop ad hoc networks. We propose and have implemented PDP, a path density recording protocol. In this paper we describe PDP, discuss protocol design options and explain how it was piggybacked onto an existing reactive routing scheme. We assess the validity of our approach both using simulations and real world measurements.
